CNN -- Newly-appointed Aston Villa manager Gerard Houllier will take control of the squad after Saturday 's English Premier League match against Bolton Wanderers .

Houllier was presented to the media as Martin O'Neill 's successor on September 10 , but was unable to begin work with his new club due to his current role with the French Football Federation -LRB- FFF -RRB- , where he is a technical director .

The former Liverpool and Lyon manager 's first game in charge will be a Carling Cup clash against Blackburn Rovers on September 22 , but he will be present at Villa Park to see Aston Villa take on Bolton this weekend .
